[Mrs. Don-o]

I very much appreciate the fact that the traditional Church officially canonizes but does not officially demonize. We sometimes (by miraculous divine intervention) know that a person is in heaven, but we do not know whether a person is in hell. This has not been revealed to us.

This is why we can pray in all sincerity, along with the Guardian Angel of Portugal (Fatima 1916):

O my Jesus,
Forgive us our sins,
Save us from the fires of Hell.
Lead all souls to heaven,
Especially those in most need of Thy mercy.

Why do I say this? Because Salvation is still a mystery in the hands of God, like the unbaptized, ostensibly nonChristian poor Jew Lazarus at rest--- as Christ said --- in the bosom of Abraham.

Which is what the document you object to, said: "That the Jews are participants in God's salvation is theologically unquestionable, but how that can be possible without confessing Christ explicitly, is and remains an unfathomable divine mystery."

Tagline.

Because Salvation is still a mystery in the hands of God

There is no mystery here:

1 John 5:13  These things have I written unto you that believe on the name of the Son of God;
that ye may know that ye have eternal life,
and that ye may believe on the name of the Son of God.

1 John 5:20  And we know that the Son of God is come,
and hath given us an understanding,
that we may know him that is true, and we are in him that is true,
even in his Son Jesus Christ.
This is the true God, and eternal life.

No, the document is saying is that “the Jews” as a whole can be saved without explicitly accepting Christ. It is not speaking about individual souls who may or may not be invincibly ignorant.

The document speaks heresy. You can either accept that and deal with it or you can choose to continue to explain it away like Jimmy Akin and his ilk and live in ignorance.
